Product details

The 1N6276ARL4 is a 1500W peak pulse power Zener TVS diode from onsemi's Mosorb™ series, designed for general-purpose transient voltage suppression in through-hole applications. It offers a reverse standoff voltage of 13.6V, a minimum breakdown voltage of 15.2V, and clamps at 22.5V maximum, making it suitable for protecting 12V nominal rails from surges.

onsemi has marked the 1N6276ARL4 as Obsolete, meaning no ongoing production. Remaining stock on tape and reel is the only source. If your BOM needs this exact part, request a quote for available inventory — we source from multiple distributor channels and can confirm current availability at quote time. For new designs or long-term support, plan a cross-reference to an active TVS with similar 13.6V standoff and 1500W rating in a DO-201AD or surface-mount equivalent.

Frequently asked questions

Is the 1N6276ARL4 obsolete?

Yes, onsemi lists the 1N6276ARL4 as Obsolete. No further production is planned. Remaining stock is limited to existing inventory.

What is the best replacement for 1N6276ARL4?

A direct replacement should match the 13.6V reverse standoff, 15.2V breakdown, 22.5V clamping, and 1500W peak pulse rating. Look for active TVS diodes in the Mosorb™ family or other brands with the same DO-201AD package. onsemi does not list a specific successor; cross-reference against parts like the 1N6276A series (non-tape-and-reel suffix) or an equivalent Littelfuse / Vishay TVS with identical voltage thresholds.
